Abstract (en)

[origin: LU101374B1] In its first aspect, the invention concerns a process for providing an extract of phytosterols and stanols from tall oil pitch with the steps of (a) providing a mixture of neutral matters from tall oil pitch; (b) performing a distillation on said mixture of neutral matters, so as to provide a distillate fraction; (c) dissolving said distillate fraction into mixed solvents, so as to provide a dissolved distillate fraction. Said process is remarkable in that it comprises a step (d) of crystallization performed on said dissolved distillate fraction so as to recover a mother solution and a crystallized fraction forming an extract of phytosterols and stanols and in that said mixed solvents of step (c) comprise apolar solvents, solvents having a ketone moiety, monohydric alcohols and water. In its second aspect, the invention concerns an extract of phytosterols and stanols which is free of oxysterols, ?-sitosterol and betulin.
